Uni can you PM me your address and I will get these posted out to you. Bad news im afraid I can't find the tins of weights anywhere so will have to send without. The G500 does have the cartridge in it and a few weights but the G5 has nothing.
No worries, I believe a mate used to have a G5, may still have some weights, if not I will just use some spare led I have laying around if it is needed
